Today, 450 motor boats, 115 houseboats, 300 canoes, thousands of row boats, and a dozen sail boats ply Kansas City's three rivers, and it is estimated that $400,000 is invested in various kinds of pleasure water-craft in the city.Kansas City is built upon an almost square tract of land with rivers upon three of its sides. The Kaw flows along its western border, the Blue flows through the eastern border, and the northern side of the square is the Missouri RiverKansas City TimesJune 23, 1978
